Rosa plant named ‘LIMkiss’

ABSTRACT

A new and distinct  Rosa  cultivar named ‘LimKiss’ is disclosed, characterized by a vigorous, climbing plant habit and flowers colored deep magenta. Flowers have a strong, spicy scent. Plants can be grown on their own roots and are strongly resistant to black spot. The new variety is a  Rosa , normally produced as an outdoor garden or container plant.

Latin name of the genus and species: Rosa hybrida.

Variety denomination: ‘LIMkiss’.

BACKGROUND OF THE INVENTION

The new Rosa cultivar is a product of a planned breeding program conducted by the inventor, Peter Ping Lim. The objective of the breeding program was to produce vigorous new garden rose varieties for ornamental commercial applications. The cross resulting in this new variety was made between April and June 2010.

The seed parent is the unpatented variety Rosa ‘Ebb Tide’. The pollen parent is the unpatented variety Rosa ‘Golden Eye’. The new variety was selected in June of 2011 by the inventor in a group of seedlings resulting from the 2010 crossing in a research nursery in McMinnville, Oreg.

Asexual reproduction of the new cultivar was performed by vegetative cuttings. This was first performed at a research greenhouse in McMinnville, Oreg. in June 2011 and has shown that the unique features of this cultivar are stable and reproduced true to type in more than 5 successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘LIMkiss’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘LIMkiss’ These characteristics in combination distinguish ‘LIMkiss’ as a new and distinct Rosa cultivar:

-   -   1. Double flowering tea rose with a vigorous plant habit.     -   2. Climbing plant habit.     -   3. Continuing flowering double hybrid tea flower.     -   4. Deep magenta coloration.     -   5. Strong spicy fragrance.     -   6. Can be grown without grafting, performs vigorously on its own         roots.     -   7. Easy to propagate and root.     -   8. Resistance to black spot disease.

Plants of the new cultivar ‘LIMkiss’ are similar to plants of the seed parent, in most horticultural characteristics, however, plants of the new cultivar ‘LIMkiss’ differ in the following:

-   -   1. The new variety has a climbing habit, the seed parent does         not.     -   2. The new variety has a magenta colored flower, the seed parent         has a purple flower.

Plants of the new cultivar ‘LIMkiss’ are similar to plants of the pollen parent in most horticultural characteristics, however, plants of the new cultivar ‘LIMkiss’ differ in the following;

-   -   1. The pollen parent has red colored flowers, the new variety         has magenta flowers.     -   2. The new variety has a double flower, the pollen parent has a         single flower.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘LIMkiss’ can also be compared to the commercial variety Rosa ‘William Buffin’, unpatented. These varieties are similar in most horticultural characteristics, however ‘LIMkiss’ differs in the following:

-   -   1. The new variety has a larger flower than this comparator.     -   2. The new variety is more fragrant than this comparator.     -   3. The new variety is less heat and drought resistant than this         comparator.

Plants of the new cultivar ‘LIMkiss’ can also be compared to the commercial variety Rosa ‘Tabone’, U.S. Plant Pat. No. 5,633. These varieties are similar in most horticultural characteristics, however ‘LIMkiss’ differs in the following:

-   -   1. The new variety has a climbing plant habit, this comparator         does not.     -   2. The new variety produces more branches than this comparator.     -   3. The new variety is more disease resistant than this         comparator.     -   4. The new variety has a stronger fragrance than ‘Tabone’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH
